Specification of Letters Patent.

Patented Sept. 28, 1909.

Application filed April 27, 1909. Serial No. 492,479.

To all'whom it may concern:

lie it known that'I, DAVID E. MoN'm, a citizen ofthe United Sta-tes,residing at Genesee Depot, in the county of Waukesha and State ofllviscoiisin, have invented certain new and useful Improvements inSilos; and I do hereby declare the following to be a fullclear, andexact description of the invention, such as Will enable others skilledin the art to which it appertains to make and use the same.

My invention relates to new and useful improvements in silos and myobject is to construct a device of this class which vwill be air tightwhen properly closed.

A further object is to provide a double wall to form an air space.

A further object is to provide a passage way in connection with thesilo, whereby the contents of the silo may be removed and depositeddirect from the passage into a buildfurther object is to provide achamber in one wall of the silo and place a ladder therein wherebyaccess may be had to the silo at any'point in its height- A furtherobject is to provide windows in parts of the silo to admit light theretoand a still further object is to provide suitable drainage for the silo.

Other objects and advantages will be hereinafter referred to and moreparticularly pointed out in the claims.

In the accompanying dra-wings forming part of this application, Figure 1is a central vertical sectional view through the silo and passagetherefor, and, Fig.l 2 is a transverse sectional viewvthrough the siloat a. point above the passage,

.Referring to the drawings in which similar reference numerals designatecorresponding parts throughout the several views, l and 2 indicate theouter and inner walls, respectively, of the silo, which wallsl areconstructed of any suitable material, suc-l as stone, brick, cement. orthe like,'and are spaced apart to form an air space 3, the two wallsbeing interlocked with each other by means of bars l as shown in Fig. Q,the ends of the bars heilig seated in the walls. The walls l and 2 areplaced upon a foundation 5, which may be constructed of any suitablematerial` a base plate (3 being introduced between the wall andfoundation, while a similar plate -T is placed on the upper ends of thewalls, said plates being preferably formed of cement and provided withgutters 8 and 9, respectively, which gutters ter1ninate in spouts 10 andare adapted to carry water away from the outer wall of the silo toprotectthe same from dampness.

Resting upon the plate 7 -is a dome 1l. which is preferably constructedof brick and covered with any suitable coating such as coal tar, or thelike, a coating of sand being then placed over the dome while the tar isin a soft state and in View of the arch of the dome, it will be selfsupporting. The dome is provided with an opening 12 in which is seated aframe t3, said opening forming a space for filling the silo and in orderto seal the silo, the frame 13 is to be covered With glass 14 or liketransparent substance, thereby admitting light to the interior of thesilo and in addition to the opening in the dome, it is provided with a.vent 15, in its apex. Y

Extending vertically of the walls 1 and 2 is a chamber 1G, which is ot'sufficient width to admit the body of a person and vextends the fullheight of said walls and by providing steps 17 on one wall of thechamber, access may. be readily had to the interior of the silo at anypoint in its height. The inner face of the chamber'lG communicates withthe interior of the silo and in Vorder to close communication betweenthe chamber' and silo, boards, or the like 1S, are introduced into theopening between the chamber and silo, said boards being placed one uponthe other and introduced into position as the silo is filled or ifpreferred, all of the boards may be placed in position before fillingthe silo.

Communicating witlrthe lower portion of the silo is a passage 19, wl ichis ot sutlicient height to admita person therein and is preferablylocated below the ground, the end farthest from the silo communicatingwith the interior of av building 2() and in order to securely close thepassage, the open ing therein is provided with an air tight door 2l,which when closed will, prevent the entrance of air into the silo atthis point.

One wallof the chamber 1G is provided with a ywindow 22, the object ofwhich is to-pro'vide light for the exterior of the chamber and by making'the frame 23 containing the window, air tight, the air will be excludedfrom the siloat this point.

In order tol gain access to'y the interior of the dome 1,1. the bars 24vare secured to the loo outer face' of the wall l so that the wall of thesilo can be readily scaled to remove the cover from the opening 12 orplace the same in position thereover or for other p urposes desired. l

In filling the silo, the glass is removed from the frame 13 and thecontentsfto be placed in the Asilo, entered through the opening and asthe silo fills with the ensilage, the boards are to be placed one abovethe other until the top of the chamber 16 has been reached, any suitablemeans for retaining` the boards in position, being employed. After thesilo has been filled, the glass is again placed over the frame 13 and ifit is desired to make the silo air tight, the vent 15 is also closed andthefsilo can be maintained in this condition as long as the open- .ingsinthe dome and the door 21 are kept communicates with the passage sothat ready access may be had to the chamber at all f times.

IVhat I claim is: i 1. The herein' described silo construction,comprising Walls hav/ingan air space therebetween, a foundation for saidwalls, plates arranged above and below' said walls, said ranged upon theupper' one oflsaid plates,"v l with its base located adjacent to thedrainage channel of said plate, the base of the'outer one of said wallsalso being arranged adjaplates having drainage channels therein, thechannels in each plate discharging at a com-- mon point, laterally lofsaid walls, a dome arcent to the drainage channel of the lower baseplate.

2. A' device of the character described, comprising walls having anintermediate air space, a foundation for said walls, plates arrangedabove and below said walls, having drainage channels therein, a domesuperposed with relation to the upper one of said plates, a laterallsupplemental chamber arranged exteriorly of said walls and communicatingwith a chamber formed by said walls, a subterranean passageco1nmunicating with the First referred to chamber and having an entrancebeyond said first referred to chamber.

A de'vice of the character described, comprising walls having an airspace therebetween, a foundation for said walls, plates arranged aboveand below said walls, having drainage channels therein, a dome arranged'upon the upper plate,'with its basecontiguons to the drainage channelof s'aid plate, the

outer one of said walls having its base arranged adjacent to thedrainage channel of the lower one of said plates, an undergroundpassageway communicating with the chamber formed by said walls, saidpassageway having a closure at its end distant from said chamber, and anadditional chamber extending vertically with relation toi said walls andopening into the chamber formed thereby, said supplemental chamber beingarranged exteriorly of said walls'and communicating at itsA lower endwith said. underground pas ,sageway, said supplemental chamber beingvprovided wlth means for ascending the same., p

and means for forming a temporary closure between said wall-.formedchamber and said supplemental' chamber.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses. i y y DAVID E. MONTA. Witnesses:4 T. DAVID EDWARDS,
